SPECIFICATION forming part of Letters Patent No. 709,703, dated September 23, 1902.

Application led March 18,1902. Serial No. 98,714. (No model.)I

To @ZZ 1071/0777/ if; 711,601/ concern:

Be tknown that I, THOMAS J. FORDE, a citizen of the United States, residing at Geneva, in the countyof Ashtabula and State of Ohio, have invented certain new and useful Improvements in Oarbureting Apparatus; and I do declare that the :following is a full, clear, and exact description ofthe invention, which will enableothers skilled in the art to which itappertains to make and use the same.

My invention relates to carbureting apparatus; and the invention consists in an apparatus constructed substantially as shown and described, and particularly pointed out in the claims.

In the accompanying drawings, Figure lis a vertical sectional elevation of the apparatus. Fig. 2 is a sectional elevation ot' a set of valves for controlling the flow of the vapor or gas from the said apparatus to the main, as hereinafter fully described. Fig. 3 is a perspective elevation of a form of generator-coil used with this apparat-us. Fig. i is a vertical sectional elevation of the apparatus at right angles to Fig. l and substantially through the center thereof. Fig. 5 is a horizontal sectional plan of the base for a generator-coil and certain other members associated therewith. Fig. G is a vertical sectional elevation of a form of oil-filter used with this invention.

The apparatus as thus shown and described is intended to be placed in some con-` venient position in or about the building or buildings Where the gas is to be used, and in residences the said apparatus may safely be placed in the cellar; but the oil-tank from which it is supplied should be kept under cover on the outside of thebuilding, Where there can be no possible danger of explosion if for any reason explosion might occur. I-Iowever, if the heavier grades of hydrocarbon be used, such as kerosene, the tank containing the oil may Very safely be placed in the cellar, and no danger need be feared from an explosion.

Referring to Figs. l and 3, A represents a generating-coil in which the oil is converted into gas or vapor for supplying the saine for use, and the said coil is shown as formed out of comparatively thin metal, such as brass or copper tubing, and'soft, preferably, so that the extremities thereof may be dared to produce flanges a', by which an effective coupling of the pipe is made without packing or other similar means for preventing leakage. The formation of this coupling is illustrated in Fig. 5. As already indicated, the gas or vapor mannfactureijl in this producer is of a iiXed kind which will not condense and which Will travel after the man ner of ordinary illuinitiating-gases and especially as far and as satisfactorily as may be desired Within the limits of a building, or possibly a few adjacent buildings, to which a single apparatus of this kind is generally limited.

The coil A as shown here is supported upon an annular base B, which hasaduct b across the same, Fig. 5, open to said pipe A and connected therewith by means of a coupling comprising a coupling-nut N and a projection engaged upon a rightangled projection In and bearing against a collar or sleeve n2 on tube A, VWhich itself presses; against flange ct of said tube or pipe. This connects end a of pipe A with generator-base B, While the other end goes to the source of oil-supply through filter F, as will be seen..

Valves 2 and 3, respectively, control the flow of the gas from the generator-base B, and the jet or opening controlled by valve 2 is practically the secondary burner-jet, which discharges into one branch or arm of a substantially T-shaped inem ber B'. This branch or portion on the part B' opposite the jet or valve 2 serves as a mixing-tube, and the stem ot' said part B opens up through the base B and discharges into the interior of the coilheating or main burner B2.

The burner B2 is substantially of a cup shape, inverted to rest upon the base B, and is ot' two diameters, with its upper half reduced to attach the coil A and perforated in one or both of its elevations to promote the escape of vapor and to provide a burnerflame upon the outside thereof to heat said coil.

2 and also communicates with duct or passage b and opens duct b3 to base B and which issues through body D, where valves d and d control the outflow of gas. In the passage ofthe gas or vapor from duct b3 it travels The valve 3 is nearly directly opposite valve l IOO through the duct c in the cap C, which rests over the coil A and has down-fiange c2, adapted to more orless gather the heat arising from burner B and promote the further heating of the coil. The said cap Cis connected by bolts 6 through the return tube or pipe J, so that the parts B, C, and J are mechanically connected and practically rigid with each other. A small standard b4, Fig. 1, is socketed in an arm of base B and in the bottom of cap C at one side and serves to make a rigid connection at that side.

The secondary initial burner-valve 2 of course is closed when the apparatus is under way and the valve 3 is open, because then all the vapor or gas travels hence through the producer and has no supply connection with main burner B, excepting the overilow'which comes from the gaspassage in t-he head G. It will be noticed that the gas or vapor proceeding through ducts b3 and c and admitted through valves d or d', or both, enters the mixing-tube g, whence the mixture passes by elbow g4 to head g'. The main G, which leads off to the building, is connected with the top of head g'; but a return-pipe g3 from the head g' drops down beneath .burner B2, Fig. 4, and connects with the opposite branch of the T-shaped part B. At this point there is aflip-valve b5, adapted to be turned to close the discharge from valve 2 or the down discharge through pipe g3, as here shown. If turned in the opposite direction, the said pipe g would be open except to its controllingdamper g2. By means of said damper the operator can control the quantity of mixed gas which shall flow from head g' dow-n into the burner B2 to sustain the Haine for maintaining generation in coil A. Any suitable construction of damper or valve g2 may be used for this purpose. The main body of gas or vapor produced is carried off through the main orpipe Gto the building` for use.

The tube J is used for two purposes. In the rst place it serves as an air-supply to the mixer g through the pipe J, which enters tube Gat its bottom and lowest end and which presumably goes to the outside of the building for fresh air, and it may be provided with a suitable chamber or valve to control the iniow of air, if that be found necessary. It is furthermore provided with a downwardlyinclined bottom adapted to discharge into the down-pipe J through elbow A2, so that any condensations of vapor that, may occur will be carried off through the oil-supply pipe, thus keeping the parts clear of oil. A suitable drum or casing A/ incloses the generatorbase B and the coil A, the cap C, and associated parts, so that the heat generated by the main burner is confined Within this space or casing and the work of generation is promoted. The tube .I is furthermore provided with a removable cap 8 at each end, through which easy admission is effected thereto for cleansing or other purposes.

As a primary or first lighting and heating 4another as it descends and in its exposure be evaporated by the atmosphere, and thus pass down through the tube H2 to the extremity I-I3 thereof, Fig. l, Where it is provided with a burner h3 at its extremity and may be lighted by a match or taper. It will be noticed that the said extremity or initial burner h3 comes directly beneath and outside the base B within casing A and in position to heat all of said parts to a vaporizing state and especially the generatorbase. When this has been done, the valve 2 may be turned on and the source ofsupply through the vaporizing-chamber H cut od. Then when the parts are brought to the desired state ot heat the valve 2 may likewise be closed, valves 3 and d and d opened, when the burner B2 will be supplied with mixed vapor and air from the downpipe g, as already described. Then the apparatus is ready for a continuous run.

It is essential in an apparatus of this kind that the oil should be as thoroughly cleansed as possible before it enters into the passages of the apparatus. To this end I bring the oil through a suitable lter F in the oil-supply channel through pipe P and through which the flow of the oil is controlled by a valve f. The said filter has a suitable filtering mediaf, designed to be of a character which will absolutely cleanse the oil of all impurities which are not of a strictly iiuid kind, and connected with the filter at its top is the pipe f2, which is practically a portion of the coil-pipe A, and the pipe P', which conveys the oil to the initial vaporizing-cliamber II, and valve h at the top of said chamber, Fig. 4, controls the flow of oil thereto. The said lter has a removable bottom f, which enables the filtering material to be removed and replaced.

It will be noticed that the mixer-tube g is adjustably supported, so as to provide for the admission of more or less air through the tube to chamber J.

What I claim isl. In a gas-carbureting apparatus, a generating-coil, a generating-base on which said coil issupported having a valve-controlled gas-duct open to said coil, a main to which the gas iows from the coil and a mixer at the opening for the gas into the said main, substantially as described.
